Thus, eliminating the tedious process of chain surveying to measure horizontal distance. Tacheometric surveying is preferred over chain or tape surveying. It is faster and more convenient, especially in […]

The two common types of drone mapping methods are photogrammetry and LiDAR. Both the methods give different mapping outputs and require specific data processing software to study the data. This article discusses the common maps delivered after a drone […]

Real-time kinematic (RTK) is another type of correction technology like PPK but performs real-time corrections to the data and images. PPK technique is commonly used in drone mapping and land surveying. PPK […]

Theodolites can be either digital or non-digital types. Digital theodolites are more convenient and accurate as they provide digital readouts instead of reading directly from the traditional graduated circle. This article […]
